The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] The driving mechanism 20 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0031] Reference Figure 1-Figure 2 According to the driving mechanism 20 of the embodiment of the utility model, the driving mechanism 20 is used for the magnetic levitation transport device 100, and the magnetic levitation transport device 100 includes an arc-shaped turning track 13 and a mover 15 movably arranged on the turning track 13.

[0032] The driving mechanism 20 includes a turntable 21, a driving motor 22 and an insertion rod 23. The turntable 21 is arranged on one side of the turning track 13 and the rotation axis coincides with the axis of the turning track 13.

A plug plate is provided on the side of the mover 15 facing the turntable 21, and a plug hole 151 is provided on the plug plate. The insertion rod 23 is movably provided on the turntable 21 along the axial direction of the turntable 21 to extend into the plug hole or extend out from the plug hole. The insertion rod 23 is spaced apart from the rotation axis of the turntable 21.

[0033] The insertion rod 23 is spaced apart from the rotation axis of the turntable 21, so that the insertion rod 23 can move along the axial direction of the turntable 21 and can also rotate around the rotation axis of the turntable 21 with the turntable 21. When the mover 15 moves to the turning track 13, the insertion rod 23 of the driving mechanism 20 moves along the axial direction of the turntable 21 and is inserted into the corresponding insertion hole 151 of the mover 15. The driving motor 22 drives the turntable 21 to rotate, and the turntable 21 drives the insertion rod 23 to rotate around the rotation axis of the turntable 21. The rotation axis of the turntable 21 coincides with the axis of the turning track 13, so that the insertion rod 23 can drive the mover 15 to rotate around the axis of the turning track 13, so that the driving mechanism 20 can drive the mover 15 to move on the turning track 13, and can improve the stability of the mover 15 moving on the turning track 13.

[0034] According to the driving mechanism 20 of the embodiment of the utility model, when the mover 15 is located on the turning track 13, the insertion rod 23 of the driving mechanism 20 can extend into the insertion hole 151 of the mover, thereby driving the mover 15 to move on the turning track 13, which can improve the stability of the mover 15 moving on the turning track 13.

By providing the guiding slopes 242 at both ends of the protrusion 241 in the length direction, the guiding slopes 242 can guide the movement of the insertion rod 23, so that the insertion rod 23 can move relatively smoothly from the protrusion 241 part of the cam disc 24 to the part without the protrusion 241, and can also move relatively smoothly from the part without the protrusion 241 of the cam disc 24 to the part with the protrusion 241.

[0048] Reference Figure 1-Figure 6 According to the second embodiment of the utility model, the magnetic levitation transport device 100 includes a track member 10, a mover 15 and the above-mentioned driving mechanism 20. The track member 10 has a track, and the track includes a straight track 12 and a turning track 13 connected to each other. A straight stator is provided on the straight track 12, and the turning track 13 is an arc track. The mover 15 is movably arranged on the track, and the mover 15 is a plurality of movers 15 arranged at intervals along the length direction of the track. The plurality of movers 15 are arranged at intervals along the circumferential direction of the annular track 11, so that there is a sufficient safety distance between adjacent movers 15, which can reduce or avoid the occurrence of collisions between two adjacent movers 15.

[0049] The mover 15 is provided with a magnet, and the linear track 12 drives the mover 15 to move by magnetic suspension. The driving mechanism 20 is arranged opposite to the turning track 13. The turntable 21 is arranged on one side of the turning track 13 and the rotation axis coincides with the axis of the turning track. The mover 15 is provided with a plug plate on the side facing the turntable 21, and a plug hole 151 is provided on the plug plate. When the mover 15 is located on the turning track 13, the plug rod 23 extends into the plug hole 151. When the mover 15 is located on the linear track 12, the plug rod 23 is disengaged from the plug hole 151. The linear track 12 drives the mover 15 to move by magnetic suspension. When the mover 15 moves on the linear track 12, the insertion rod 23 disengages from the insertion hole 151, the mover 15 disengages from the driving mechanism 20, a magnet is provided on the mover 15, and the linear track 12 drives the mover 15 to move by magnetic suspension. For example, the linear stator of the linear track 12 is provided with a coil, and the coil forms a magnetic field after being energized, and can interact with the magnet on the mover 15 to push the mover 15 to move along the linear track 12. In addition, the linear track 12 drives the mover 15 to move by magnetic suspension, so that the mover 15 can have a higher transportation speed and higher conveying accuracy on the linear track 12.

This can prevent the magnetic field to which the mover 15 is subjected from becoming smaller after it moves to the turning track 13, thereby causing the mover 15 to have a lower speed and acceleration during the movement of the turning track 13.

[0051] Optionally, two annular guide rails 14 can be symmetrically arranged on both sides of the track member 10 in the axial direction, and the mover 15 is provided with a matching groove that matches with the two guide rails 14.

[0052] Optionally, the linear track 12 can also provide a supporting force for the mover 15 through magnetic suspension to ensure the stability of the movement of the mover 15 .

Figure 1-Figure 3According to some embodiments of the utility model, there are two linear rails 12 that are opposite to each other and arranged at intervals, there are two turning rails 13 that are arranged at intervals, the linear rail 12 is located between the two turning rails 13, the two linear rails 12 and the two turning rails 13 are connected end to end to form a ring, and the driving mechanisms 20 are two correspondingly arranged in correspondence with the two turning rails 13. The structure is relatively simple, and the processing and manufacturing difficulties are relatively low, and the mover 15 can move smoothly on the annular rail 11. For example, the rail is an annular rail 11, and the annular rail 11 includes two linear rails 12 and two turning rails 13. The two linear rails 12 are arranged between the two turning rails 13, and the two linear rails 12 can be arranged in parallel, one end of the two linear rails 12 is respectively connected to the two ends of one of the turning rails 13, and the other end of the two linear rails 12 is respectively connected to the two ends of the other turning rail 13. The mover 15 of the annular track 11 can move along the circumferential direction of the annular track 11, which is conducive to realizing functions such as automated transportation and transfer. The workpiece that needs to be transferred, such as the pole piece, can be fixed to the mover 15 and follow the mover 15 to move along the circumferential direction of the annular track 11 to the corresponding position, which can improve the transfer efficiency and improve the safety and accuracy of the transfer.

[0054] In addition, in the related art, when the magnetic levitation transport device 100 is used in a vertical application, that is, the axis of the turning track 13 of the circular track 11 is parallel to the ground or the operating table, and the linear track 12 is parallel to the horizontal plane, if both the linear track 12 and the turning track 13 use magnetic levitation to drive the mover 15 to move, when the mover 15 stays on the turning track 13, the magnetic levitation needs to continue to work to overcome the gravity of the mover 15 itself, the power consumption is relatively serious, and long-term stay can easily cause the track part 10 to overheat. In addition, when the magnetic levitation transport device 100 is powered off, the mover 15 located on the turning track 13 will slide down along the turning track 13 under the action of its own gravity, which can easily cause collisions between movers 15, and the safety is low.

[0055] By providing the driving mechanism 20, during the use of the magnetic suspension transfer device 100, the working state of the driving motor 22 can be controlled according to the specific use situation. When the mover 15 needs to stay on the turning track 13, the driving motor 22 stops rotating, the turntable 21 and the plug rods 23 arranged along the circumference of the turntable 21 stop rotating, and the plug rods 23 are inserted into the plug holes 151 of the mover, so that the mover 15 can stay on the turning track 13 more stably, and the transfer device 100 does not need additional work to overcome the gravity of the mover 15 itself. In addition, by providing the driving mechanism 20, it is possible to avoid the situation where the mover 15 located on the turning track 13 will slide down along the turning track 13 under the action of its own gravity after the transfer device 100 is powered off, thereby improving the safety and flexibility of the transfer device 100.
